Before I get into the advice, I have to say the top thread in this forum section tells you everything you need to know about installing liberty 3. The title is even "[ROM] Liberty 3 For The Droid 2 11/04 - It's Time For A Revolution!." It's fine if you didn't look for a thread, but so many people put "I couldn't find anything when I searched" in their posts when the answer is only one or two threads further down the forum.

Now on to the help.

You need to SBF back to stock froyo so you can get the official gingerbread update. Liberty 3 is based on that update, whereas liberty gb was based on the leaked gingerbread. Once you have the official gingerbread release, root your phone and install liberty 3 via clockwork. That's it.
